Condensation on Windows

Struggling with condensation on my bedroom window.Double glazed window (10+ years old). Sleep with door closed, heating off and blinds closed. It has become worse over last few weeks (with the colder weather).

Get new glass. Don’t change the windows if they’re ok only the sealed units

Nope they just need to open the windows

You need air circulating to help prevent moisture build up.

Although I have all the small windows in my flat so that they are slightly open (don't know what you call that setting on double glazed windows), and my door is open, but in winter I get a lot more condensation.

I think it's more because the curtains restrict the airflow at certain points.

I have a dehumidifier, but it's noisy and takes a few hour to do it's thing.

It's all about maintaining a reasonable humidity as any moisture in the air will turn back to liquid once it finds a cool surface.To do this you need to regularly ventilate the room, regularly heat the room and don't introduce any more moisture into the air than necessary. Breathing is a big cause (that you can't do much about!) but any type of clothes drying (without running a dehumidifier) is a no no and always keep bathroom doors shut to prevent steam escaping to other parts of the house. We're just in the process of overhauling how we treat humidity in our flat and have just bought a dehumidifier from Aldi - it's very eye-opening when you see just how much water it removes from the air! After a few days of concentrating on different areas of the flat we now get no condensation at all.

Open all your doors & windows for 5 minutes before you go to bed. This will reduce the relative humidity and the general temperature wont be affected for longer than 10 minutes after closing them.

Basically agree with all of the above. What I will say is using a dehumidifier maybe a cure, it's better to try and reduce the condensation to start with.Yes you can change the glass, however I'd be surprised if it would solve your problem, although it may help to reduce it.The best thing is heating your property to a stable temperature, ventilation, and do not dry clothes indoors. Think if you had a condensing tumble dryer would you throw the water onto the walls and floors, as that is exactly what your doing if you dry your clothes indoors.Finally you can buy small and very cheep humidity sensors with a digital readout. These are a great way to determine if you have a damp problem or a condensation problem. Your humidity should be about 55 to 65%.Hope that helps.
